"The marriage of Nullsoft and AOL was always one of discontent. After AOL acquired the small company in 1999 for around $100 million, the young team of Winamp developers was assimilated into a strict corporate culture that begged for rebellion. Although Nullsoft was initially given a long leash by AOL, it wasn't long until the two ideologies collided."
Sometimes, all it takes for a project or an office or whatever to fall apart is the loss of one person. The resignation of Nullsoft founder and Winamp creator Justin Frankel last January seems to have done just that. The era of Nullsoft seems to be coming to an end, with the original Winamp team having said goodbye to AOL. Apparently, only a skeleton team remains working on Winamp, just doing minor maintainence work. No further improvements to Winamp are expected, period. Essentially, Winamp is effectively over.
